What is a bait aerator?

A bait aerator is a device used to add oxygen to live bait, typically minnows or worms, that are used for fishing. It consists of a housing with a chamber to hold the bait and a rotating impeller that agitates the water to create bubbles and increase the oxygen content. The impeller is usually powered by a battery or a hand-cranked mechanism.

The purpose of a bait aerator is to keep the bait healthy and lively by providing them with oxygen. This is especially important when the bait is being stored or transported for an extended period. Without adequate aeration, the bait may become stressed, weakened, and die.

Bait aerators are commonly used by fishermen who prefer to use live bait for fishing. They are also used in bait and tackle shops to keep the live bait in good condition.
